Jesus allowed that they unjustly condemned him and executed him. He voluntarily stepped into the role of innocent accused, falsely convicted. He was completely innocent of the crime, he is holy and pure. Even Pilate understood that he was innocent. Through the prosecution, judgment, torture, execution, and then the resurrection, Jesus has the power to forgive sins, because he himself belongs to those who themselves suffered very hard. He also has the power to give eternal life. This can be given to you if he gets to be your Lord but also your friend.

In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence. Although he was a son, he learned obedience through what he suffered. And being made perfect, he became the source of eternal salvation to all who obey him, being designated by God a high priest after the order of Melchizedek.Hebrews 5:7-10

Indeed, because it was weak and ineffective, the former commandment has been annulled, (for the law perfected nothing), but a better hope is introduced, through which we draw near to God.
None of this happened without an oath. For others became priests without an oath,
but He became a priest with an oath made by the One who said to Him: The Lord has sworn, and He will not change His mind, You are a priest forever.
So Jesus has also become the guarantee of a better covenant.
Now many have become Levitical priests, since they are prevented by death from remaining in office.
But because He remains forever, He holds His priesthood permanently.
Therefore, He is always able to save those who come to God through Him, since He always lives to intercede for them.
For this is the kind of high priest we need: holy, innocent, undefiled, separated from sinners, and exalted above the heavens.
He doesn't need to offer sacrifices every day, as high priests do--first for their own sins, then for those of the people. He did this once for all when He offered Himself.
For the law appoints as high priests men who are weak, but the promise of the oath, which came after the law, appoints a Son, who has been perfected forever.Hebrews 7:18-28

For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my laws into their minds, and write them on their hearts, and I will be their God, and they shall be my people. And they shall not teach, each one his neighbor and each one his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest. For I will be merciful toward their iniquities, and I will remember their sins no more.” When He said, "A new covenant," He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear.Hebrews 8:10-13

But when Christ appeared as a high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation; and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption. For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?Hebrews 9:11-14

For Christ has entered, not into holy places made with hands, which are copies of the true things, but into heaven itself, now to appear in the presence of God on our behalf. Nor was it to offer himself repeatedly, as the high priest enters the holy places every year with blood not his own, for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself. And just as it is appointed for man to die once, and after that comes judgment, so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him.Hebrews 9:24-28

For it is impossible for the blood of bulls and goats to take away sins. Consequently, when Christ came into the world, he said, “Sacrifices and offerings you have not desired, but a body have you prepared for me; in burnt offerings and sin offerings you have taken no pleasure. Then I said, ‘Behold, I have come to do your will, O God, as it is written of me in the scroll of the book.’”Hebrews 10:4-7

Then he said, "Look, I have come to do your will." He cancels the first covenant in order to put the second into effect. For God's will was for us to be made holy by the sacrifice of the body of Jesus Christ, once for all time.Hebrews 10:9-10

For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a fearful expectation of judgment, and a fury of fire that will consume the adversaries.Hebrews 10:26-27

How to be saved, to become a Christian
Believe in what Jesus Christ did for you on the cross and that He is the living son of God, that He died for your sins and rose from the dead. Say aloud with your mouth that He is the Son of God, that He died for your sins and rose from the dead. Confess Him as your Lord.
This is the major step. But then as a result of this it is natural that you try to live by His commandments and also pray for forgiveness for the things that you have done wrong in your life, your sins. The son of God and God himself will forgive you if your prayer is sincere.
Be baptized in Jesus' name if you are not already baptized.
If you can't speak, just think the words, God hears you.
